- Primary Mission Objective:
Explore the basic physics of particle acceleration and energy release in solar flares
Science Objectives
Solar:
bullet Determine the frequency, location, and evolution of impulsive energy release in the corona
bullet Study the acceleration of electrons, protons, and heavier ions in flares
bullet Study the heating of plasma to tens of millions of degrees and determine its relationship to particle acceleration
bullet Study the propagation and evolution of energetic particles in flares
bullet Determine the relative abundances of accelerated and ambient ions in flares
Non-Solar:
bullet Obtain images and spectra of the Crab Nebula with 2 arcsecond spatial resolution and ~1 keV spectral resolution
bullet Detect and obtain high resolution spectra of gamma-ray bursts and cosmic and terrestrial transient sources over a large fraction of the sky
bullet Search for cyclotron line features in gamma-ray bursts and cosmic transient sources
bullet Obtain high resolution spectra and search for line features in steady X-ray and gamma-ray sources
